The Two Co st ai ts That Limit High Speed Visio Systems

Eve y visio system that images a movi g subject meets the same two co st ai ts at the se so level. The fi st is the shutte a chitectu e. A olli g shutte se so eads pixel ows i seque ce, so the top of the f ame is captu ed at a diffe e t i sta t tha the bottom. Whe the subject moves du i g that i te val, the f ame is skewed, a d eve y measu eme t de ived f om it ca ies a spatial e o that o co ectio fully emoves. O a co veyo u i g at 1.5 mete s pe seco d, a eadout i te val of a few milliseco ds displaces the bottom of the f ame by seve al millimete s, a d gaugi g, optical cha acte ecog itio , a d defect classificatio i he it that e o .

The seco d co st ai t is ba dwidth. F ame ate o a y USB i te face is bou ded by the p oduct of pixels pe f ame, bits pe pixel, a d f ames pe seco d. O ce that ceili g is eached, the o ly way to acqui e faste is to se d fewe pixels. E gi ee s have histo ically d opped to a lowe – esolutio se so , bi ed at the cost of spatial detail, o c opped o the host afte the f ame has al eady c ossed the bus. The fi st two optio s disca d optical i fo matio pe ma e tly, a d the thi d does othi g fo ba dwidth o late cy.

The Falco -235CGS add esses both co st ai ts i o e module. Global shutte captu e f om the O semi Global Shutte Image Se so emoves tempo al skew at the pixel level, a d Dy amic ROI moves c oppi g i to the se so ‘s eadout path, so ba dwidth eleased by a smalle wi dow co ve ts i to a highe f ame ate.

That is the diffe e ce betwee a cosmetic c op a d a ge ui e High F ame Rate USB Came a.
